To all whom it may concern.-

Beit known that I, J AMEs DAVIE, a subject of the Queen of Great Britain, residing at Crosshill, Glasgow, Scotland, have invented evaporating water or other liquids; and one object thereof is to provide an'improved apparatus for this purpose which may be used at sea' to evaporate salt water, so as to pro- ,duce potable water and water for steam-boil-.

ers, a further object being to produce a device of this class which may be easily cleaned and which is of great capacity,-while occupying but small space, a further object being to provide an apparatus of the class described which may be used wherever such devices are required and for concentrating sugar and for many other and similar purposes; and with these and other objects in view the invention consists in the construction, combination, and arrangement of parts hereinafter described and claimed.

The invention is fully disclosed in the fol lowing specification, of,which the accompanying drawings form a part, in which Figure 1 is a side elevation of one form of my improved evaporating apparatus,the main casin g being shown in central vertical section Fig. 2, a similar view at right angles to Fig. l with one side of the main casing-removed; Fig. 3, a plan View; Fig. 4, a view similar to Fig. 1, showing a modification, the top portion of the apparatus being removed; Figs. 5 and. 6, sectional details of the construction; Fig. 7, a View similar to Fig. 1, showing another modification; Fig. 8, a front viewof the apparatus shown in Fig. 7, part of the casing being removed; and Fig. 9, a plan view of said ment are designated by letters of reference it may be secured to a wall or other support, and at the point where the parts of said casing meet they are provided each with a flange a by which they are bolted together, as shown at a Fig. 3. The part A is provided at the top and bottom thereof with tubular collars a and a respectively, and within the main .casing, composed of the parts A and A is placed a steam-coil B, which is also substantially spherical in form,and one end of the pipe is provided with an upwardly-directed portion 1) and the other with a downwardlydirected portion b and these portions may be formed integrally with or separately from and be connected with the main coil B. The end portions 12 and b of the coil B are in line With the vertical axis of the main casing, so that when the coil B isin position in said casing it may be turned on its Vertical axis by hand, so asto facilitate the cleaning and scaling of the salt and other defects which have been depositedon the heating-surface. The coil B may 'be held in position bynuts O O and O or in any desired manner, and the portion 19 of the coil B is preferably provided with a rigid collar 0 andsaid coil is put in position by removing the nut C and unscrewing the nut C and letting it drop down on the portion b of the coil B,.after which the said portion b is passed upwardly through the collar a until the bottom portion b can be inserted into the flange of, when the coil B is let down until it issupported by the collar 0 and the nuts 0 C ,and O are screwed into position. A steamsupply pipe D is connected with the coil B through the portion b, which is provided with a coupling (1, and said steam-supply pipe D is provided witha valve 02 Fig. 2, and the lower end of the portion 1) is provided ,with a coupling 01 with which is connected a drainage-pipe d4, provided with a valve (1 The bottom of the'statio'nary part of the main casing, composed of the parts A and A is provided with a blow-off and drain E, having a valve e, and connected with one side of the main casing is a water-gage F, and connected with the opposite side of said casing in each of the views, and 1n the practice of my invention, as shown in Figs. 1 to 3, inclu-' sive, I provide a main spherical casing composed of two parts A and A and the part A is provided with a side bracket a, by which lsa water-supply plpe Ur, provided with a valve g.
